MOISE : MOuillage Instrumenté et Suivi biogEochimique

Medium and long term observation of the coastal environment in New Caledonia. Climatic variability in tropical zones. Evolution of the monthly, seasonal and interannual variability of the hydrological and biogeochemical characteristics of marine waters at a point located off the Bay of Dumbéa (N-NW of Noumea, New Caledonia) on a depth of 10m.

Measurement of the impact of natural and anthropogenic forcings on the environment, study/quantification of the consequences of this variability, both natural and anthropogenic, on the structuring and functioning of the pelagic ecosystem, and in particular on the appearance of diazotrophic blooms.

Validation of the images obtained by different ocean color sensors by monitoring the variations of the "water color" for an adjustment of the algorithms of calculation of the chlorophyll obtained from satellite reflectance. Possible measurements of the impact of the atmospheric plume of the SLN (Société Le Nickel = nickel treatment by pyrometallurgy) following preliminary work.

Supplemental Information: You can customize the template to suit your needs.

You can add

and remove fields and fill out default information (e.g. contact

details).

Fields you can not change in the default view may be accessible in the

more

comprehensive (and more complex) advanced view. You can even use the

XML editor

to create custom structures, but they have to be validated by the

system, so

know what you do :-)

Statement: MOISE is composed of a mooring on a shallow (8m) coral reef included in the ReefTemps ("Basse Caui") network measuring every quarter hour temperature, salinity and fluorescence, of a currentometer, and a station sampled monthly using CTD vertical profiles and surface-bottom sampling.

Profiles 0 - 8 m temperature, salinity, turbidity, fluorescence

On surface-bottom sampling: suspended solids, nutrients, particulate matter (CHN), stable isotope 13C/15N, chlorophyll, microbial communities (flow cytometry), pigments
